The setup is the most important than anything else in removing rust inside the fuel tank. Besides, work procedures and working methods, to experience a variety of cases because different depending on the occurrence situation of rust, various applications come to live by knowing.
What I definitely want to know is that you can't "uproot" the rust that has occurred unless you remove dirt such as tar covering the rust iron plate!!
Again, let's thoroughly "set up" before using rust removal chemicals.
Thoroughly remove the rust anything that physically rusted!
When you look into the inside of the fuel tank through the tank cap hole, you'll find a lot of dirt and rust in there. In such a case, the previous article "Key Points for Successfully Removing Rust from Fuel Tank! Removing Dirt is Necessary Before You Work!" But by using the introduced "number line", it is possible to remove the physical rust and dirt by scraping from the fuel cap mouthpiece. Rust that rubs off inside the fuel tank should be removed as much as possible before using high-performance chemicals. In fact, "judgment before starting work" is quite important in removing the dirt and rust inside the fuel tank. When you look inside the fuel tank with the LED light, you can see that the inside of the fuel tank is dry? Or is it "damp" with rotten fuel! First of all, it's important to understand the current situation.
If it's dry and rusting, blow the inside of the fuel tank with a long nozzle air gun or use a wire to scrape out as much dirt and rust from the inside as possible.
If it's just rust from the looks of it, you can proceed with the work from this stage using a high-performance rust removal chemical.
However, if there is a rotten fuel smell from inside of the fuel tank, or if there is obvious moisture, you should proceed with the work step by step. First of all, you should remove the fuel dirt thoroughly. Cleaning the inside of the fuel tank and high-pressure cleaning with "neutral detergent = Mama Lemon" described in the previous report is effective.
If there is still a "persistent dirt" that cannot be removed, you can start the work here. It should be possible to perform fairly sophisticated fuel tank cleaning.
If the metal fittings of the fuel cock are the fitting type of the pipe screw, the lid can be created by using the pipe cap and the leg rubber of the table that can be purchased at the home center, and the liquid leakage can be prevented.
Y'S GEAR "super carburetor cleaner (undiluted solution type)" that is used by motorcycle mechanic staff. Dilute 3 parts of the cleaner solution to 7 parts of the fuel tank according to the instructions to thoroughly decompose carbon dirt. Originally for carburetor cleaning, this is really effective! You may reuse the waste liquid after carburetor cleaning.
Y'S GEAR commercial carburetor cleaner is amazing!!
After filling up with fuel mixed with a commercial carburetor cleaner, while checking the fall of the dirt (it is best to check the inside by putting the processing liquid in and out), the processing liquid fuel is pumped out. Then pump the fuel out of the treatment liquid.
Refresh the parts with degreasing cleaning liquid or neutral detergent.
Remove the fuel system inside the fuel tank with a neutral detergent or commercial degreasing cleaner (again, reusing used liquid). If the tar and varnish of deteriorated fuel still remain, wash it again.
Finally, its time to practice rust removal in a full-fledged fuel tank with high-performance chemicals. Before that, let's rinse the inside of the fuel tank again with tap water and shine a light on it to check the internal condition. The important thing is to remove the dirt of "oil and tar" on the rust.
- A commercial carburetor cleaner is effective for cleaning deteriorated fuel in the fuel tank!
- High-performance chemicals that work well for rust removal are not strong enough to deal with dirt.
“Preparation” is the most important factor in removing rust from the fuel tank. As I mentioned in the previous setup commentary, (1) emission of rotten fuel. (2) Such as dirt by altered fuel, it is important to thoroughly remove before rust removal practice.
The dirt inside the carburetor greatly affects the engine condition. In most cases, the cause of carburetor contamination is due to "residual fuel alteration". In other words, the dirt inside of the fuel tank is also caused by "deteriorated fuel". We recommend the use of the "carburetor cleaner" to clean the inside of the fuel tank.
In particular, our motorcycle mechanic editorial department is good at using the "commercial super carburetor cleaner (stock solution type)" released from Y'S GEAR, which is also OEM YAMAHA specification. This product is a high-performance carburetor cleaner that dissolves the sticky, pasted fuel, tar, and varnish by diluting the specified dilution solution of high-performance chemicals with fuel. The carburetor cleaner is used not only for its original use, but also for "cleaning the fuel tank" located upstream of the carburetor.
The large amount of waste fuel that has been washed can be stored in a carrying can or an liter can and used as an oil stain remover around engine parts and drive chains. The cleaning capability is extremely high. Please try it
